综合光谱技术（UV-vis、拉曼、XPS、XAS 和 EPR）显示，钒硅酸盐沸石 AM-6 含有交替 V=O 和 V-O 键的线性链。这些链中的 V(IV) 离子是铁磁耦合的，并且通过一维海森堡模型获得了与磁化率数据的良好拟合，J = 0.66(1) cm(-1)。因此，AM-6 是第一个报道的结合一维铁磁链的微孔材料的例子。
The vanadosilicate zeolite AM-6 is shown by a combination of spectroscopic techniques (UV-vis, Raman, XPS, XAS and EPR) to contain linear chains of alternating V=O and V-O bonds. The V(IV) ions in these chains are ferromagnetically coupled, and an excellent fit a to the susceptibility data with a one-dimensional Heisenberg model is obtained with J = 0.66(1) cm(-1). AM-6 is thus the first reported example of a microporous material incorporating one-dimensional ferromagnetic chains.
